JULES JOHN JOSEPH RYGKE, OF NEW? YORK, N. Y.

STEAM SEPARATOR AND GREASE-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 617,480, dated January 10, 1899. Application filed July 29,1898. Serial No. 687,164. on model.)

T0 to whom it may concern;

Be it known that I, JULEs J OHN J OSEPH DE RYOKE, a citizen of the United States, residing in New York, (Brooklyn,) in the State of New York, have invented a certain new and useful Improvement in Steam-Separators and Grease-Extractors, of which the following is a specification.

The invention relates to that class of separators and extractors in which a baffle-plate located in the path of the steam causes the latter to be deflected from a direct course and deposit the entrained water and grease upon the plate and adjacent surfaces of the casing, whence it is collected and removed.

The object of the invention is to provide an apparatus that shall be simple in construction, easily and cheaply manufactured and operated, and will efficiently perform the required functions.

It consists of a casin g having a centrally-located internal tube provided with a transverse diaphragm or baffle-plate lying in the path of the steam entering through an inletpipe arranged opposite to the mouth of the tube and extending inwardly toward the diaphragm. The steam is projected into the tube, strikes the diaphragm, and is reversed in direction and escapes between the tube and casing to the outletpipe, leaving its grease and water on the surfaces. The passages are large and practically unobstructed, allowing the steam to flow freely, but compelling it to make .the sudden reversal. In the most complete form of the apparatus the steam is forced to make a similar quick change in direction on the opposite side of the diaphragm in entering the outlet-pipe. Provisions are made for collecting any grease or water thus eliminated and lead it through protected passages to a chamber below in communication with a tank in which it is stored, and means are provided for emptying the tank and chamber at intervals and-for preventing the ingress of air during the operation or liability of mechanically carrying over any of the entrapped grease or water by a sudden inrush of air through the drain-pas sages.

The invention also consists in certain details of construction and arrangement of parts to be hereinafter described.

The accompanying drawings form a part of this specification and show the invention as I have carried it out.

Figure 1 is a central Vertical section through the separator and extractor arranged to serve on a horizontal steam-pipe, certain portions being shown in elevation. Fig. 2 is a corresponding partial elevation and vertical section of the upper portion of Fig. 1. Fig. 3 is a vertical section showing a modified form adapted to serve on a vertical steam-pipe.

Similar letters of reference indicate like parts in all the figures.

Referring to Figs. 1 and 2, A is a casing, preferably of spherical form, thickened and faced at A" A on opposite sides to receive the flanges B O of the steam-pipes B O, and A is a tube located centrally within the casing, joined to the latter above and below by the thin webs A and having the lower portion dished, as at A and provided with a depending pocket A. A diaphragm A extends across the interior of the tube, completely closing it. The tube is preferably so located within the casing that its axial line coincides with the axial line of the inlet and outlet steampipes B O and their inward extensions B 0 These extensions or thimbles are provided with narrow flanges 13 0 received in corresponding counterbores a a formed in the faces A A and serving to hold the thimbles reliably in line when the pipes B O are bolted in place. Each thimble extends inwardly and lies with its month Within the tube, and one (the thimble C is provided with a fin or ridge 0, surrounding it, and a lug 0, matching to a corresponding notch in the casing, to insure the proper position in the latter when the parts are assembled. A similar ridge or fin a extends around the tube A in the depression a at the center and includes the pocket A in its circuit.

The lower portion of the casing is open and faced, as at A to receive the flange D of a chamber D, secured thereto,and within which depend the pipes A", leading downward from the pocket A, one on each side of the diaphragm A At the lower end of the chamber D is an outlet-pipe D controlled by a valve D leading to an intermediate receiver E, connected by a pipe E, controlled by a valve E to a tank F, drained by a pipe F and valve F The chamber D and tank F are provided with glass gages D F and the intermediate receiver E and tank F are equipped with the air-cocks 1L F.

G is a pipe extending from the upper part of the tank to a point in the inlet-pipe B and is controlled by the valve G.

The operation of the separator is as follows: Steam under pressure enters through the pipe B and is projected within the tube A striking against the diaphragm A and reversing its direction escapes through the annular space between the thimble B and the tube, which space is greater in areathan the pipe and allows the steam to flow freely in the new direction. A portion of the water will be deposited upon the diaphragm and inner surface of the tube and trickle down the surfaces,

to be caught in the pocket A and led through the pipe A to the chamber D below and out of the steam-current. The steam is then again forced to reverse by turning the edge of the tube and finds a large open annular passage between the tube and inner face of the casing obstructed only by the thin vertical webs A, supporting the tube and the fin a on the exterior of the latter, serving, with the circumferential depression a, to conduct downward any water deposited on its outer face. The direction of the current is again abruptly changed by turning the outer edge of the tube and is projected against the opposite face of the diaphragm and again reversed to enter the thimble C and outlet-pipe C. The momentum of the water in turning the edge of the tube will project it against the outer surface of the thimble C and adjacent inner face of the casing, and to prevent such water being again taken up by the current of steam passing below the tube I provide the fin 0, serving to lead it downward behind the shield M, where it is protected from the current while flowing downward into the chamber. The water deposited within the tube and upon the diaphragm flows to the pocket A and thence through the pipe A to the chamber, which when full may be emptied by blowing or trapping out, as usual, through the pipe D NVhen serving as a grease-extractor with a condensing-engine, the action is in all respects similar to that above described, the difference being that instead of steam under pressure exhaust is passing on its way to the condenser, and it is highly important when thus used that the air be excluded during the emptying operation to avoid impairing or destroying the vacuum. The system of pipes and valves connecting the chamber with the intermediate receiver and tank is intended to serve in successfully performing that function.

\Vhen the extractor is in operation, the aircocks E 1 are closed, as is also the valve F and the valves D E and G are "open to equalize the pressure and allow the grease and water to flow to the tank F and accumulate therein until it requires draining. This is effected by closing the valves G and E thus cutting off the tank from communication with the condenser, opening the air-cock F and valve]? to allow the contents of the tank to escape through the pipe F. During this period the collection of water and grease continues and accumulates in the intermediate receiver E, which is of such capacity as to take the drainage while the tank is emptying, and is removed therefrom by closing the valve D and opening the air-cock E and valve E thus allowing the accumulation to flow into the tank and escape through the pipe 1*",as before. To again condition the apparatus for service, the valve F and air-cocks E F are closed to prevent further ingress of air, and then the valve G is opened to reestablish an equilibrium of pressure between the tank and receiverE and the condenser. The small quantity of air thus admitted is received in the inlet-pipe B and flows through the extractor with the current of steam and is removed by the air-pump, as usual. The valve D is last opened, and as equilibrium has been estab lished the downward flow of the grease and water commences without encountering any opposition.

An advantage of importance is attained by locating the pipe G between the tank and inlet-pipe in that any grease or water carried upward mechanically will be caught by the current of steam before entering the extractor and will be deposited by the action of the latter, and thus prevented from reaching the outlet-pipe O and the condenser.

The pipe II, controlled by the valve II, es tablishes communication between the upper part of the tank and the chamber D above the water-line and is intended as an alternative device. In the operation of emptying and again restoring equilibrium this pipe may be used instead of the pipe G above described. The air admitted through it is received in the upper portion of the chamber above any accumulation of grease and water in its lower part, flows to the condenser, and is removed, as before. The pipe H will successfully perform the functions required; but any water or grease carried by the air will not be so surely eliminated as in the pipe G.

Instead of draining the tank F when it is full, or nearly so, the water and grease may be allowed to accumulate until the tank and intermediate receiver E are filled and a considerable quantity is collected in the chamber D. The operation of emptying is, however, the same as before described.

L L are gratings consisting of concentric bars in the same plane separated by V-shaped slots Z, opening outwardly and joined at intervals by thin webs L. They are applied one on each face of the diaphragm and held in place by bolts and at a distance from the face of the diaphragm by the lip or flange L The flange is omitted at the lower portion, so

. that any waterthrown through the grating ICC IIO

may fiow downwardly to the pocket. The general outline of the grating is circular or elliptical, and an apron L provided at the lower edge, protects the water trickling down the diaphragm behind the grating from the incoming steam.

It will be observed that in passing from the inlet to the outlet pipe the steam is nowhere choked or forced to pass through contracted passages. The flow is free; but the steam is compelled to abruptly reverse its direction or whip-snap four times before it escapes, and the water or grease thrown out by momentum against the surfaces is quickly protected and led away without further exposure to the rapidly-moving current.

The apparatus occupies but little space and may be easily and cheaply manufactured.

Modifications may be made'in the forms and proportions within wide limits, and parts of the invention maybe used without the whole.

When serving as a separator, the pipe G, intermediate receiver E, tank F, and pipe I-I may be dispensed with and any suitable steam-trap substituted.

The gratings L may be omitted or modified and the general'construction of the'casing varied.

The form shown in Fig. 3 is designed to serve with a vertical steam-pipe. The chamber D incloses the elongated thimble B and the diaphragm A arranged horizontally, is domed to, provide a gutter a from which extends a pipe A, leading the water and grease to the chamber. The drain-pipes are attached at the side, as shown, and may lead to an intermediate receiver and tank similar to the construction shown in Fig. 1.
